Solar PV powered cathodic protection for a buried

Cathodic protection is employed intensively on the steel drains in oil and gas industry. It is a technique of prevention against the corrosion which transforms the structure into a cathode of a corrosion cell. This can be achieved either by using a more active sacrificial anode to create a driving current, or by using inert anodes and impressing a current onto the cathode surface using an external direct current (DC) source. ICCP needs a constant DC power supply that is usually provided through a grid connection or independent generators. The paper presents the possibility and the way of applying cathodic protection system by impressed current supplied with solar energy panels applied to a buried pipeline.
